Let me try to understand your question here, and I suppose you're talking about DVD Decrypter. It is recommend to use the Mode, File F on DVD Decrypter to rip and decrypt any encrypted protection codes into your hard drive first, then afterward, do what you mainly do to encode a movie and burn it with any of your desire burning engine. Mode, Iso, Read R to your hard drive is good especially for ripping and burning PS2 games and DVD9 (DVD+R DL) backups. "IFO I" - I'm not sure about this one, since I haven't used it yet, but I'm sure someone with the knowledge will answer you in due time.
